Description
Technical field
The utility model relates to snow removing equipment technical field, specifically a kind of roller brush support wheel resetting-mechanism.
Background technique
Currently, the roller brush support wheel of existing snow removing vehicle for aerodrome is usually by support shaft, support wheel, tension spring, bearing and rotation
Pivoted housing composition, the support shaft lower end are fixedly connected through bearing with rotary sleeve, and the rotary sleeve lower end is solid through wheel carrier and support wheel
Fixed connection, the tension spring upper end are hinged with support shaft, and lower end is hinged with support wheel, and when the snow removing of airport, vehicle is often
It need to turn around, turn and frequent swing roller brush device, since this structure only installs reset tension spring at support wheel, when support wheel is put
When angle is excessive, tension spring is excessively stretched, and spring is caused just to fail using very short time, causes frequently to replace tension spring.
Summary of the invention
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, provides a kind of structure novel, avoids spring mistake
Divide stretching, performance stabilization, roller brush support wheel resetting-mechanism with long service life.
The utility model solves technical solution used by above-mentioned technical problem:
A kind of roller brush support wheel resetting-mechanism, including support shaft, support wheel, tension spring, bearing and rotary sleeve, it is characterised in that
It further include guide-rail plate, fixed plate, float plate, limited roller and wheel shaft, the guide-rail plate is eccentric plectane, and the guide-rail plate is most
Short radius side semicircle end face is waveform bumps guide pass, and the guide-rail plate is fixed on rotation set upper side through bolt, described to lead
Fixing sleeve is connected to fixed plate in support shaft above rail plate, and the fixed plate side radially extends to form tension spring connecting rod, another
Side radially extends to form hinge bar, and described float plate one end is hinged through pin shaft and hinge bar, and the other end connects through tension spring and tension spring
Extension bar is connected, and the float plate is equipped with wheel shaft, and the wheel shaft lower end is equipped with limited roller, the limited roller and waveform
Concave-convex guide pass is in contact, and when support wheel rotation, guide-rail plate is rotated with support wheel, and limited roller then rotates and edge with guide-rail plate
The waveform bumps guide pass relative rotation of guide-rail plate, limited roller resistance is applied to by waveform bumps guide pass, is made
Tension spring slow stretching, when support wheel pivot angle maximum, support wheel is swung in place at this time, and limited roller is located at the waveform of guide-rail plate
Make resistance maximum at the maximum radius of concave-convex guide pass one end, support wheel stops rotating, avoids tension spring excessive tensile, work as branch
When return is wanted in support wheel swing in place, under the drive of tension spring, limited roller drives the support wheel below guide-rail plate and guide-rail plate certainly
Dynamic return solves tension spring mistake at work since idler wheel remains at the rail length rotation of waveform bumps guide pass
Divide and stretches and cause the substance of failure insufficient.
The utility model can also be equipped with locating piece in the float plate side, and the fixed plate is equipped with block in place, works as institute
After stating tension spring reset, locating piece and block in place are inconsistent, in favor of preventing tension spring from causing during return due to inertia force
Compression rebound ensure that the performance of support wheel is stablized.
The utility model has structure novel, avoids spring from excessively stretching, performance stabilization, makes due to using the above structure
With the service life it is long the advantages that.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the top view of Fig. 1
Fig. 4 is the cross-sectional view of A-A in Fig. 1.
Appended drawing reference: support shaft 6, support wheel 1,2 guide-rail plate 8 of tension spring 16, bearing 4 and rotary sleeve, fixed plate 17, float plate
10, limited roller 11 and 20 hinge bar of wheel shaft 12 pin shaft, 19 tension spring connecting rod, 21 locating piece 22 and block 23 in place.
Specific embodiment
The present invention will be further described with reference to the accompanying drawing:
As shown in the picture, a kind of roller brush support wheel resetting-mechanism, including support shaft 6, support wheel 1, tension spring 16,4 and of bearing
Rotary sleeve 2,6 lower end of support shaft are fixedly connected through bearing 4 with rotary sleeve 2, and 2 lower end of rotary sleeve is through wheel carrier 3 and support
Wheel 1 is fixedly connected, it is characterised in that and it further include guide-rail plate 8, fixed plate 17, float plate 10, limited roller 11 and wheel shaft 12, it is described
Guide-rail plate 8 is eccentric plectane, and the most short radius side semicircle end face of the guide-rail plate is waveform bumps guide pass, the guide rail
Plate 8 is fixed on 2 upper end of rotary sleeve through bolt, and fixing sleeve is connected to fixed plate 17 in the support shaft 6 of 8 top of guide-rail plate, described
17 side of fixed plate radially extends to form tension spring connecting rod 20, and the other side radially extends to form hinge bar 21, the float plate 10
One end is hinged through pin shaft 19 and hinge bar 21, and the other end is connected through tension spring 16 with tension spring connecting rod 20, the float plate 10
It is equipped with wheel shaft 12,12 lower end of wheel shaft is equipped with limited roller 11, the limited roller 11 and waveform bumps guide pass phase
Contact.
The utility model can also be equipped with locating piece 22 in 10 side of float plate, and the fixed plate 17 is equipped with block in place
23, when the tension spring 16 reset after, locating piece 22 and block 23 in place are inconsistent, in favor of prevent tension spring during return due to
Inertia force and cause compression rebound, ensure that support wheel performance stablize.
When support wheel rotation, guide-rail plate is rotated with support wheel, and limited roller is then with guide-rail plate rotation and along guide-rail plate
Waveform bumps guide pass relative rotation, limited roller resistance is applied to by waveform bumps guide pass, keeps tension spring slow
It stretches, when support wheel pivot angle maximum, support wheel is swung in place at this time, and limited roller is located at the waveform bumps guide rail of guide-rail plate
Make resistance maximum at the maximum radius of face one end, support wheel stops rotating, and tension spring excessive tensile is avoided, when support wheel is swung
When wanting return in place, under the drive of tension spring, limited roller drives the support wheel self-return below guide-rail plate and guide-rail plate, when
For locating piece with when block contacts in place, tension spring stops retraction, during return, leads since idler wheel remains at waveform bumps
The rail length of rail level rotates, and solves tension spring and excessively stretches at work and cause the substance of failure insufficient.
The utility model has structure novel, avoids spring from excessively stretching, performance stabilization, makes due to using the above structure
With the service life it is long the advantages that.
